A lawyer says the number of children sexually or physically abused by priests while serving in a choir run by Pope Emeritus Benedict’s brother at their Catholic school in the German city of Regensburg totals 231. That’s more than three times as many cases as had been reported previously by the church.

Ulrich Weber, a lawyer hired by the church,announced the new cases Friday as part of his continued investigation into the scandal concerning Domspatzen which is the official choir for St. Peter’s Cathedral in Bavaria, Germany. The first allegations of sexual abuse were made public in 2010 when a well-known composer named Franz Wittenbrink told the German magazine Spiegel he had been abused while enrolled there.
